Package in unusual place outside front of restaurant (6)
I believe the answer is:
parcel
'package' is the definition.
('parcel' can be a synonym of 'package')
'unusual place outside front of restaurant' is the wordplay.
'unusual' indicates an anagram.
'outside' indicates putting letters inside.
'front of' suggests taking the first letters.
The first letter of 'restaurant' is 'r'.
'place' is an anagram of 'pacel'.
'pacel' going around 'r' is 'PARCEL'.
'in' acts as a link.
(Other definitions for parcel that I've seen before include "Package wrapped in paper" , "Wrapped container" , "plot" , "Wrapped present" , "Package; piece of land" .)
